In Oral Implantology equipped with facilities for more accurate examination and diagnosis, we conduct various tests such as medical CT examination before surgery. We provide implant treatment to each patient in a well-organized manner by making a team with other clinical departments.

Director of the department

Kaoru Kusano


In our department, we try to have the patients fully understand the implant treatment through interview and preoperative tests so that patients can visit us at ease. The attending dentists will carefully explain the advantages and disadvantages comparing with the prosthodontic treatment, such as dentures, bridges, and artificial teeth, in light of the oral environment of each patient. We work with other clinical departments to ensure that patients receive comfortable treatment.

Characteristics of dental care

1. Treatment consultation/examination/diagnosis

Before offering a dental implant, we determine whether or not the treatment is indicated by conducting various tests. First, the local and systemic conditions are examined to see if an implant is appropriate. Then, we explain the procedures and risks of implant treatment and the necessity of X-ray and blood tests, etc.

explanation to patient



2. Implant surgery

An artificial root called implant body is implanted in the bone of the jaw. If the patient is afraid of surgery or anxious about the general condition such as hypertension, we can perform the procedure under sedation in cooperation with an anesthesiologist. With sedation, the patient can undergo the surgery in a relaxed state like half asleep. In general, an artificial tooth cannot be used instantly after the surgery of implant body. It usually needs several months for the implant body to connect to the jawbone.

<Superstructure of implant>
What is important for implant is not only surgery in which the implant is placed into the gum. The superstructure that corresponds to a tooth is also important. Generally, a temporary tooth is placed after the implant binds to the bone so that the patient can see what it is like. We adjust the shape of the tooth and the condition of the surrounding mucous membrane with the temporary tooth. We will make a new tooth by consulting with the patient, dentist, and dental technician about the shape and color of the temporary tooth.

3. Maintenance

Regular maintenance is essential to keep the implant for a long period of time and in a good condition. The condition of the implant and surrounding gum and occlusion, etc. will be checked in regular maintenance. The health of entire mouth, including implant, will be cared through daily brushing by the patients and specialized cleaning in our department.

Efforts for state-of-the-art dental care

Hyperostosis (bone grafting)

Creating the bone necessary for implanting

Sinus lift/socket lift

Dental implants cannot be sometime placed due to a large cavity (maxillary sinus) in the maxillary. In that case, the bone necessary for implanting is created in the cavity.

Mucosal graft/connective tissue graft

Creating the gum when there is not enough gum (gingiva) around the implant.
